Abstract
A formulation technology for low pressure two component polyurethane foam-funning compositions containing gaseous hydrohaloolefin blowing agents is described with improved storage stability and extended shelf-life. The 'B'-side component of the formulations contain a gaseous hydrohaloolefin blowing agent and a polyol pre-mix, the polyol pre-mix comprising liquid blowing agent, polyol, and a catalyst containing at least one catalytic metal compound.
